SPECIFICATION forminggpart of Letters Patent No. 260,046, dated June 2'7, 1882,

Application filed April `20, 1882. (No model.)

To all whom it may concern Be it known that I, WILLIAM H. PAGE, a citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Steam Heaters, of which the following is a speciiication, reference being had therein to the accompanying This invention pertains to improvements in,l steam-generators, having for its object chieiiy to eiiect the partial heating of the water before bringing it into contact with the tire-pot or other highly-heated surfaces of the generator preparatory to its conversion into steam, to thoroughly subject it to the heat ot' the generator, to fully utilize the heat of the products of combustion upon the steam chamber and pipes, and to prevent the direct contact of the products of combustion with the walls of the tire-pot and it consists ofthe combination and arrangement of parts substantially as herein-v said chamber. Gast or formed upon the inner surface of the fire-pot or wall A' is a series of vertical V-shaped ribs or bars, b, having air- C', united to the lower edge of theouter case or shell. This bottom plate forms the crownsheet of the re-pot, and therefore receives the direct action of the products of combustion to effect the better heating of the water in the chamber C. This chamber has a steam exit or egress pipe, d, fromwhich, by other pipes, the steam is conducted to a steam-radiator or other place where desired.

D D are return-pipes from radiators and the Water-supply pipes, arranged one on each side of the generator, for feeding the water thereto at either side, as may be desired. The vertical portions D of either supply-pipe can be connected to a pipe of the water-main or other head of water, and is designed to have a supply and cut-oft' cock. The vertical pipes D are connected to curved pipes D'. The pipes D' are arranged on each side of and a short distance below the top of the dome of the steamchamber G and connected to a short pipe, e. This pipe e is closed at its outer end and discharges into the steam-chamber C in the same plane with the arrangement of the pipes D', as clearly seen in Fig. 2.

The curved pipes D' are adapted to stand out beyond the vertical pipes D, and the masonry is built with a space, E, between it and that part of the generator below and above the pipes D' and in front of them. This causes the heat and'products of combustion issuing from the generator at the bottom between the two walls A A' to travel in a tortuous route outside ofthe generator, and thus heat the watersupply pipes and reheat the water and steam chambers. The smoke passes oft through the chimney or eXit-pipef, communicating with the space E.

F is another vertical water-pipe, with its upper end connected to the short pipe e and its lower end connected to a horizont-al pipe, G. The pipe Gr extends underV the grate-bar g of the fire-pot, and is connected to a central pin,

g', cast upon and depending therefrom, as seen in Figs. 2 and 5. This, however, may be accomplished in any other suitable way. The

IOG

pipe G exposes the water therein to the heat from the bottom of the lire-pot. It connects with the water space or chamber A5 by a short tube, h, and thus feeds water therein.

It will be observed that,the water having been subjected to the heat passed externally to the generator in contact with the supply-pipe and the pipe leading under the iregrate, it will reach the chamber formed partly by the re pot in a partially-heated state, and thus prevent the liability of the cracking of the tirepot, as would be the case were the water passed without this partial heating into contact therewith. The water-chamber A2 is connected at the front of the gencratorwith the steam-chamber G by two pipes, H, one arranged on each side ofthe chute or door thereof. rlhis arrangement permits the keeping up of' a continuous and uninterrupted circulation ofthe water in cbullition throughout the generator.

It will be remarked that the water from the supply-pipe entering the tube c in line with the supply-pipe Falter the generationof steam in the steam-chamber C will be caused by the action of the currents ofwater in ebullition to flow down into the pipe F, and thus enter the steam chamber or boiler through the pipes H ina heated state, preventing the chilling of the water in the boiler. 1t will be further remarked that the capacity of pipe F is equal to the capacity of the pipes H.

I claim and desire to secure by Letters Patent- In a steam-generator, the combination, with the annular water-chamber having heating-tubes, of the supply water-pipes leading to vertical pipe connected with a pipearranged under the fire-grate and connected with the said water-chamber, substantially as and for the purpose set forth.

2. ln a steam-generator, the combination, with the lire-pot and the surrounding waterehamber, ofthe steam-chamber snperposed upon the water-chamber, and the water-tubes connecting the said chambers together at the rear below the re-pot and in front at the top ot' said surrounding` water-chamber, substantially as and for the purpose set forth.

3. The combination, with the steam-generator adapted to allow the return and upward passage ofthe products of combustion external to itself, ot' the vertical water-supply pipes having horizontal branch pipes extending bcyond them, and thc inclosingcasingofmasonry or other suitable material, having a com bastion-space between itself and the genera tor, said space being subdivided by said branches ofthe supply-pipe from the rear to the front ends of said branch pipes, substantially as and for the purpose set forth.

In testimony whereot'I afix my signature in presence ot' two witnesses.
